    Abstract

    The reaction rates of a nonporous graphitic carbon lampblack with hydrogen gas at 865°C and 500 psi were measured following treatments such as degassing and/or oxidation with and without impregnation of K2CO3. The results lead to the conclusion that oxygen surface groups enhance the reactivity of the carbon by generating "nascent" active sites on decomposition into CO and CO2. In the catalyzed case the basic and CO carbonyl groups form active and stable surface complexes. The acidic groups, on the other hand, could not be well characterized and may form stable and inactive or unstable and active complexes depending on their nature.
